The Chetek Alert reports that Barron County health officials believe that people who became ill with E. coli infections may have become ill after eating at a fundraiser for Habitat for Humanity.

Barron County Health Officer Kaye Thompson and Randy Wilson, Barron County Sanitarian, are asking that any person that participated in the fund-raising dinner and is experiencing symptoms such as diarrhea, abdominal cramps, vomiting or fever to contact the Barron County Department of Health and Human Services and to see a physician.

E. coli O157:H7 infections can lead to complications called hemolytic uremic syndrome and thrombotic thrombocytopenic purpura, which can lead to acute kidney failure, central nervous system damage, and impairment of other major organs.
